N-ViroMotive 3GS-21B ULEL Switcher

The N-ViroMotive is the first design innovation over the single engine prime mover, which was developed in the 1950s. This rethinking of locomotive design allows the N-ViroMotive to apply a new configuration to standard rail purposes for superior results.

Replacing the single engine prime mover with three GenSets producing equal horsepower coordinated by 21st century computer and electronic controls, allows the N-ViroMotive to not only exceed the capacity of the prime movers to move freight and passengers but with unmatched reductions in NOx and PMs emissions (85-90%), noise (85%), fuel consumption (40%-60%) and maintenance costs (35-50%), NRE's N-ViroMotive is fast becoming the engine of choice.

The GenSet N-ViroMotive locomotive was developed and designed by NRE between 2001 and 2005 in response to the California Air Resources Board more stringent environmental regulations. The first engine went into service in 2007. While originally proto-typed for major Class I switching yard services in southern California and southeast Texas, the N-ViroMotive's achievement of ultra low emissions and noise as well as the significant fuel consumption savings it produces, has allowed the N-ViroMotive to expand to other markets, including short haul, passenger and mainline freight duty cycles. Today there are more than 300 N-ViroMotives in service throughout the world.
